HHF used Decibel Meter Pro to record the noise levels of hundreds of New York City subways. The samples show the average noise levels on all subway platforms and on all subway rides (inside subway trains) is between 72.5 and 76.5 dB and between 74.1 and 75.8 dB, respectively. With maximum readings actually as high as 119 dB on platforms and 120 dB on rides—based on actual recorded data within the sample—the subway system is an auditory minefield.

In other words, if you've already experienced 15 minutes at 100 dBA, you're "done for the day," and the remainder of your 24-hour period should have NO exposure above 85 dBA, and preferably should be below 70 dBA. Different levels are used for other platforms such as cinemas, DVDs, radio, video games etc. The Maximum Peak Level refers to the absolute highest level of a signal. In Europe, most television networks set this maximum peak level at -9 dBFS.
